Benefits of technology

The present disclosure can be implemented in different ways, like a collision prediction method, computer program, storage medium, or a vehicle where the collision prediction apparatus is installed. The technical effect of this disclosure is to provide a more comprehensive and effective way to predict collisions, which can help to reduce accidents and improve safety on the road.

Problems solved by technology

However, when a moving object suddenly appears from behind an obstruction such as a parked vehicle, if it takes a long time to predict a collision, a response operation such as generating an alarm may be delayed.

first embodiment

A. First Embodiment

[0019]A1. Configuration of Apparatus

[0020]A collision prediction apparatus 10 of the first embodiment shown in FIG. 1 is installed in a vehicle and predicts a collision between the vehicle and a moving object. In the present embodiment, the moving object includes movable objects and living beings such as a pedestrian, a bicycle, a motorbike, and an unmanned vehicle. In the present embodiment, the vehicle in which the collision prediction apparatus 10 is installed may be referred to as an own vehicle. In the present embodiment, the collision prediction apparatus 10 is configured by an ECU (Electronic Control Unit) including a microcomputer and a memory.

[0021]The collision prediction apparatus 10 is electrically connected to various devices installed in the vehicle and exchanges data with the various devices. Specifically, as shown in FIG. 1, the collision prediction apparatus 10 is electrically connected to a millimeter-wave radar 21, an imaging device 22, a yaw ra...

second embodiment

B. Second Embodiment

[0061]In the first embodiment, the decreased number of frames in step S135 is fixed to three. However, in the second embodiment, the decreased number of frames in step S135 is determined depending on a distance between an obstruction and a path of the own vehicle after the change of the traveling direction. The configuration of the collision prediction apparatus 10 and other procedures of the collision prediction process of the second embodiment are the same as those of the first embodiment.

[0062]In the example in FIG. 8, the decreased number of frames in step S135 differs between a case where a path Tr11 is the path of the own vehicle VL1 after the change of the traveling direction and a case where a path Tr12 is the path of the own vehicle VL1 after the change of the traveling direction. Specifically, in the case of the path Tr11, the decreased number of frames is two, and in the case of the path Tr12, the decreased number of frames is three. Such a difference ...

Abstract

The collision prediction apparatus is installed in a vehicle and predicts a collision between a moving object and the vehicle. The collision predict apparatus includes a vehicle path estimation section, a moving object path estimation section, an obstruction specifying section, a direction change information acquisition section, a moving object extraction area setting section, and a collision predict section. The moving object extraction area setting section sets, as a moving object extraction area, an area that is in the vicinity of an obstruction and is near an outer periphery of the obstruction facing a path of the vehicle after change of a traveling direction indicated by direction change information.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application is based on and claims the benefit of priority from earlier Japanese Patent Application No. 2017-127191 filed Jun. 29, 2017, the description of which is incorporated herein by reference.BACKGROUNDTechnical Field[0002]The present disclosure relates to prediction of a collision between a vehicle and a moving object.Related Art[0003]In order that an own vehicle can avoid a collision with a moving object, for example, a pedestrian, a bicycle, or another vehicle, various techniques for estimating a movement path of the moving object and predicting a probability of a collision between the own vehicle and the moving have been proposed. In such collision prediction, positions of the moving object are measured for a long time period by using a camera or a millimeter wave radar, thereby estimating a movement path of the moving object accurately and improving accuracy in predicting a probability of a collision. However, when a...
